The IBM System z9 109 (z9-109), delivering excellence in large-scale enterprise computing, is
designed and optimized for on demand business. IBM mainframes provide an advanced combination of
reliability, availability, security, scalability, and virtualization, together with the ability to
reallocate processing power, and are designed to match changing business priorities on demand.

With a modular book design, the z9-109 Model S54 is designed to provide up to 95% more total
system capacity than the z990 Model D32, and has up to double the available memory.

The Modified Indirect Data Address Word (MIDAW) facility is designed to improve FICON®
performance. The number of FICON Express2 open exchanges (concurrent I/O operations) that may be
active simultaneously has been increased from 32 to 64 per channel.

The z9-109 is focused on providing higher availability and reducing planned and unplanned outages
 which, when properly configured, may be accomplished with improved nondisruptive replace,
repair, and upgrade functions for memory, books, and I/O as well as extending the nondisruptive
capability to download Licensed Internal Code updates.

New integrated clear key encryption security-rich features on the z9-109 include support for
Advanced Encryption Standard, Secure Hash Algorithm-256, and integrated Pseudo Random Number
Generation. Performing these functions in hardware is designed to contribute to improved
performance.

Application of the z9-109 advanced virtualization technologies creates a solid foundation for
flexible integration of business and information management.

New innovations on the z9-109 can help to ensure you have a security-rich platform, can help
maximize your resources and their utilization, and can help provide you the ability to integrate
applications and data across the infrastructure. The z9-109 is designed to be a flagship component
of your heterogeneous environment.

Note:
The comparison of the z9-109 Model S54 and the z990 Model D32 is based on the LSPR mixed
workload average.

Executive summary

IBM System z9 109 (z9-109)  The next step in the evolution:
The z9-109 continues the evolution of the mainframe, building upon the structure introduced on
z990 in support of z/Architecture, reliability, availability, scalability, and clustering. The
z9-109 expands upon a key attribute of the platform  availability  to help ensure you have a
resilient infrastructure designed to satisfy the requirements of on demand business. With the
increased performance and total system capacity possible for the z9-109, you have an opportunity to
continue to consolidate diverse applications on a single platform.

The z9-109 is designed to provide:

Reduction in the impact of planned and unplanned server outages

Enhanced book availability

Redundant I/O interconnect

Enhanced driver maintenance

Dynamic oscillator switchover

Concurrent Memory Bus Adapter (MBA) fanout card hot-plug

Uniprocessor performance improvement which is expected to be up to 35% (based on LSPR mixed workload
average)

Nearly double the total system capacity of z990

Up to 54 Processor Units (PUs) compared to a maximum of 32 PUs on z990

Double the available memory per model  up to 128 GB per book

Increased host bus bandwidth between memory and I/O

Up to 16 Self-Timed Interconnects (STIs) per book, 2.7 GB each for I/O, a 35% increase in STI speed
compared to z990's 2.0 GB STI bus

Increased number of open exchanges (concurrent I/O operations) that may be active simultaneously for
FICON Express2, from 32 to 64 per channel

Up to 336 FICON Express2 channels, a 40% increase compared to z990

Availability enhancements for FICON

Additional Local Area Network (LAN) connectivity option with introduction of Open Systems
Adapter-Express2 (OSA-Express2) 1000BASE-T Ethernet

OSA-Express2 OSN (OSA for NCP), providing Channel Data Link Control (CDLC) protocol support on the
z9-109 for the IBM Communication Controller for Linux on zSeries (CCL) allowing system
administrators to configure, manage, and operate their CCL Network Control Programs (NCPs) in the
same manner as their ESCON®-attached 374x NCPs

Facilitating server consolidation

With the expanded capacity of the z9-109 and enhancements to the I/O infrastructure, IBM continues
to facilitate the consolidation of multiple servers into one z9-109. With double the memory, up to
double the number of Logical Partitions (LPARs), and four additional STIs per book, compared to
z990, you may be able to reduce the number of servers while hosting additional applications.

The performance advantage

Performance estimates with z/OS® V1.6:
IBM's Large Systems Performance Reference method is designed to provide comprehensive
z/Architecture processor capacity ratios for different configurations of Central Processors (CPs)
across a wide variety of system control programs and workload environments. For z9-109,
z/Architecture processor capacity indicator is defined with a (7XX) notation, where XX is the number
of installed CPs.

Based on using an LSPR mixed workload, the performance of the z9-109 (2094) 701 is expected to be up
to 1.35 times the z990 (2084) 301.

The LSPR contains the Internal Throughput Rate Ratios (ITRRs) for the new z9-109 and the previous
generation zSeries processor families based upon measurements and projections using standard IBM
benchmarks in a controlled environment. The actual throughput that any user may experience will
vary depending upon considerations such as the amount of multiprogramming in the user's job stream,
the I/O configuration, and the workload processed. Therefore, no assurance can be given that an
individual user will achieve throughput improvements equivalent to the performance ratios stated.
For more detailed performance information, consult the Large Systems Performance Reference (LSPR)
available at

Enhancing availability

Enhanced book availability to help reduce the impact of outages:
The z9-109 is designed to allow a single book, in a multibook server, to be concurrently
removed from the server and reinstalled during an upgrade or repair action. To help minimize the
impact on current workloads and applications, you should ensure that you have sufficient inactive
physical resources on the remaining books to complete a book removal. For maximum availability, it
is recommended that z9-109s be purchased with one additional book. If you require from one to eight
PUs, purchase a Model S18. If you require from nine to 18 PUs, purchase a Model S28, and
if you require from 19 to 28 PUs, purchase a Model S38. If you require 29 to 40 PUs, purchase
a Model S54. With such configurations, in the rare event of a book outage, all purchased PUs
can be available.

To help ensure you have the appropriate level of memory, you may want to consider the selection of
the
flexible memory option
(feature number 2802  #2824) to provide additional resources when replacing a book or when
considering plan ahead options for the future. Enhanced book availability may also provide benefits
should you choose not to configure for maximum availability. In these cases, you should have
sufficient inactive resources on the remaining books to contain critical workloads while completing
a book replacement. Contact your IBM representative to help you determine the appropriate
configuration. With proper planning, you may be able to avoid planned outages when utilizing
enhanced book availability.

Enhanced book availability is an extension of the support for Concurrent Book Add (CBA) delivered on
z990. With proper planning, CBA is designed to allow you to concurrently upgrade a z9-109 by
integrating a second, third, or fourth book into the server without affecting application
processing.

Enhanced book availability is exclusive to the z9-109.

Redundant I/O interconnect to help maintain critical connections to devices:
The z9-109 is designed to allow a single book, in a multibook server, to be concurrently
removed from the server and reinstalled during an upgrade or repair, while continuing to provide
connectivity to the server I/O resources using a second path from a different book. Redundant I/O
interconnect is exclusive to the z9-109.

Enhanced driver maintenance:
One of the greatest contributors to downtime during planned outages is Licensed Internal Code
(LIC) updates performed in support of new features and functions. When properly configured, the
z9-109 is designed to support activating a selected new LIC level concurrently. Concurrent
activation of the selected new LIC level is only supported at specific sync points (points in the
maintenance process when LIC may be applied concurrently  MCL service level). Sync points may
exist throughout the life of the current LIC level. Once a sync point has passed, you will be
required to wait until the next sync point supporting concurrent activation of a new LIC level.
Certain LIC updates will not be supported by this function.

Contact your IBM representative to help you determine the appropriate configuration. With proper
planning, you may be able to avoid planned outages when installing driver maintenance. Enhanced
driver maintenance, exclusive to the z9-109, is another step IBM is taking to help reduce the
duration of a planned outage.

Dynamic oscillator switchover:
The z9-109 has two oscillator cards, a primary and a backup. In the event of a failure of the
primary oscillator card, the backup is designed to detect the failure, switch over, and provide the
clock signal to the server transparently. Previously, in the event of a failure of the active
oscillator, a server outage would occur, the subsequent Power On Reset would select the backup, and
the server would resume operation. Dynamic oscillator switchover is exclusive to the z9-109.

MBA fanout card hot-plug:
An MBA fanout card is designed to provide the path for data between memory and I/O using STI
cables. With the introduction of the z9-109, a hot-pluggable and concurrently upgradeable MBA
fanout card is available. Up to 8 MBA fanout cards are available per book for a total of up to 32
MBA fanout cards on the z9-109 when four books are installed. In the event of an outage, an MBA
fanout card, used for I/O, may be concurrently repaired using redundant I/O interconnect (discussed
previously).

The MBA fanout card is exclusive to the z9-109.

STI granularity:
The MBA fanout card is designed to support STI granularity  two STIs per MBA fanout card (8
MBA fanout cards per book) and up to 64 STIs on the z9-109 when four books are installed. Each STI
operates at 2.7 gigabytes per second (GBps) for I/O and 2.0 GBps for ICBs.

The z990 has an MBA card, internal to the Multichip Module (MCM), and its own unique STI structure,
and is designed to support up to a total of 48 STIs per server when four books are installed. The
MBA cards on z990 cannot be hot-plugged and do not support concurrent repair.

STI granularity is exclusive to the z9-109.

Program-directed re-IPL, designed to allow Linux on System z9 to re-IPL without operator
intervention:
Linux on System z9 is designed to identify how it was IPL'd from the load device.
Program-directed re-IPL may request (by calling an LIC function) that it be reloaded from the same
load device, using the same load parameters. In this way, program-directed re-IPL allows Linux on
System z9 running natively in an LPAR to trigger a re-IPL. This re-IPL is supported for both SCSI
and ECKD devices.

This new program-directed re-IPL function is exclusive to the z9-109 and Linux on System z9. Refer
to the
Software requirements
section. z/VM® currently provides an alternate method for Linux guest re-IPL.

Capacity planning and management

Separate PU management  New flexibility for managing PUs:
PUs defined as Internal Coupling Facility (ICF) processors, Integrated Facility for Linux (IFL)
processors, or System z9 Application Assist Processors (zAAPs) are now managed separately. In the
past, ICF processors, IFL processors, and zAAPs were grouped together for allocation within and
across the LPARs.

The separate management of PU types enhances and simplifies capacity planning and management of the
configured LPARs and their associated processor resources.

Separate PU management is exclusive to the z9-109 and is supported by z/OS. Refer to the
Software requirements
section.

Improved LPAR weight management of CPs and zAAPs:
For LPARs that have both CPs and zAAPs configured, a new zAAP weight specification is provided
to allow a new unique LPAR weight specification for shared zAAPs to be defined. The existing LPAR
shared processor weight specification is now applied only to the CPs configured to the LPAR. In the
past, the existing shared processor weight specification was applied to both the shared CPs and to
shared zAAPs configured to the LPAR.

The ability to specify a separate LPAR weight for shared zAAPs helps to enhance and simplify
capacity planning and management of the configured LPARs and their associated processor resources.

Improved weight management of CPs and zAAPs is exclusive to the z9-109 and transparent to the
operating systems.

Another giant step  Now up to 60 Logical Partitions

IBM is once again doubling the number of Logical Partitions (LPARs). You now have the ability to
define up to 60 LPARs, 15 LPARs per Logical Channel Subsystem, which may provide you even more
flexibility to allocate hardware resources. With Processor Resource/Systems Manager (PR/SM)
and Multiple Image Facility (MIF) you can share ESCON and FICON channels, ISC-3s, and OSA ports
across LPARs. Support for up to 30 LPARs became available October 2003.

Support of up to 60 LPARs is exclusive to the z9-109 and is supported by z/OS, z/VM, z/VSE , TPF,
z/TPF, and Linux on System z9. Refer to the
Hardware requirements
and
Software requirements
sections of this announcement. Introduction of 60 LPARs satisfies the Statement of General
Direction in Hardware Announcement
103-142
, dated May 13, 2003.

Cryptographic support for security-rich transactions

Enhancements to CP Assist for Cryptographic Function (CPACF):
CPACF, supporting clear key encryption, is activated using a no-charge enablement feature
(#3863) and offers the following on every PU identified as a CP or IFL:

Data Encryption Standard (DES)

Triple Data Encryption Standard (TDES)

Secure Hash Algorithm (SHA-1)

CPACF has been enhanced to include support of the following on CPs and IFLs:

Advanced Encryption Standard (AES) for 128-bit keys

Pseudo Random Number Generation (PRNG)

SHA-256

PRNG is a standard function supported on the Crypto Express2 feature.

CPACF performance is designed to scale with PU performance improvements. SHA-1 and SHA-256 are
shipped enabled on all servers and do not require the enablement feature.

Support for CPACF is also available using the Integrated Cryptographic Service Facility (ICSF).
ICSF is a component of z/OS, and is designed to transparently use the available cryptographic
functions, whether CPACF or Crypto Express2, to balance the workload and help address the bandwidth
requirements of your applications.

The enhancements to CPACF are exclusive to the z9-109 and are supported by z/OS, z/VM, and Linux on
System z9. Refer to the
Software requirements
section.

Configurable Crypto Express2:
The Crypto Express2 feature has two PCI-X adapters. Each of the PCI-X adapters can be defined
as either a
Coprocessor
or an
Accelerator
.

When a System z9 with four CPs and both PCI-X adapters on one Crypto Express2 feature are configured
as accelerators, the Crypto Express2 feature is designed to perform up to 6000 SSL handshakes per
second. This represents, approximately, a 3X performance improvement compared to z990 when using
either a PCI Cryptographic Accelerator (PCICA) feature, with two PCI accelerators per feature, or
the current Crypto Express2 feature, with two PCI-X adapters per feature. The SSL performance was
achieved using z/OS V1.7 with Cryptographic Support for z/OS V1.6/V1.7 Web deliverable, and ICSF
FMID HCR7730.

Since the performance enhancements are implemented in LIC, current Crypto Express2 features carried
forward from z990 to System z9 may take advantage of increased SSL performance and the new
configuration capability.

These measurements are examples of the maximum handshakes per second achieved in a laboratory
environment with no other processing occurring and do not represent actual field measurements.
Details are available upon request.

The configurable Crypto Express2 feature is exclusive to the z9-109 and is supported by z/OS, z/VM,
z/VSE, and Linux on System z9. z/VSE, VSE/ESA, and Linux on System z9 offer support for clear
key SSL transactions only. z/VM V5.1, and later, supports clear and secure key operations.

Refer to the
Software requirements
section. Refer also to the
Special features
section of the
Sales Manual
on the Web for further information.

Note:
The previously reported SSL performance of 4995 handshakes per second
was measured on a z990 with four CPs and four Crypto Express2 features
(eight PCI-X adapters), whereas the performance on a System z9 with four
CPs was measured with one Crypto Express2 feature with two PCI-X adapters
configured as accelerators. It would be expected that the SSL
performance on a System z9 with 16 CPs and six Crypto Express2 features
(12 PCI-X adapters configured as accelerators) would be greater than that
obtained on a z990. However, actual measurements have not been taken.

Trusted Key Entry (TKE) 5.0 workstation to enhance security and
convenience:
The TKE workstation (#0859) and the TKE 5.0 level of LIC (#0855) are
optional features on the z9-109. The TKE 5.0 LIC is loaded on the TKE
workstation prior to shipment. The TKE workstation offers security-rich
local and remote key management, providing authorized persons a method of
operational and master key entry, identification, exchange, separation,
and update. The TKE workstation supports connectivity to an Ethernet LAN
operating at 10, 100, or 1000 Mbps. Up to three TKE workstations can be
ordered.

The TKE 5.0 workstation is available on the z9-109, z990, z890, z900, and
z800. Refer also to the
Special features
section of the
Sales Manual
on the Web for further information.

Smart Card Reader:
Support for an optional Smart Card Reader attached to the TKE 5.0
workstation allows for the use of smart cards that contain an embedded
microprocessor and associated memory for data storage. Access to and the
use of confidential data on the smart cards is protected by a
user-defined Personal Identification Number (PIN).

The TKE 5.0 LIC continues to support the ability to store key parts on
diskettes or paper, or optionally on smart cards, or to use a TKE
authority key stored on a diskette, or optionally on a smart card, and to
log on to the Cryptographic Coprocessors using a passphrase, or
optionally a logon key pair.

The optional TKE features are:

TKE 5.0 LIC (#0855) and TKE workstation (#0859)

TKE Smart Card Reader (#0887)

TKE additional smart cards (#0888)

The Smart Card Reader, which can be attached to a TKE workstation with
the 5.0 level of LIC, is available on the z9-109, z990, z890, z900, and
z800.

z9-109 cryptographic migration

The Crypto Express2 feature is supported on z990 and can be carried
forward on an upgrade to the z9-109.

Customers may use TKE 3.x workstations to control z900, z800, and prior
servers.

Customers may use TKE 4.x workstations to control z990, z890, and prior
servers.

Customers must use TKE 5.0 workstations to control the z9-109. TKE 5.0
workstations may also be used to control z990, z890, z900, and z800
servers.

The PCICC (#0861), PCICA (#0862), and PCIXCC (#0868) features are not
supported on the z9-109.

Enhanced performance assists for z/VM Linux guests

For HiperSockets, FCP, and OSA:
The z990 and z890 servers introduced an important virtualization technology designed to improve
the performance of z/VM guest operating systems (such as Linux on System z9) when Queued Direct
Input/Output (QDIO) is used. This virtualization technology is designed to allow QDIO interruptions
to be passed directly to guests for HiperSockets, Fibre Channel Protocol (FCP), and OSA on the
z9-109, z990, and z890 servers.

A complementary virtualization technology is being introduced for z9-109, z990, and z890:

QDIO Enhanced Buffer-State Management (QEBSM)  two new hardware instructions designed to help
eliminate the overhead of hypervisor interception

Host Page-Management Assist (HPMA)  an interface to the z/VM central storage management function
designed to allow the hardware to assign, lock, and unlock page frames without z/VM hypervisor
assistance

These new hardware assists can allow a cooperating guest operating system to initiate QDIO
operations directly to the applicable channel, without interception by z/VM, thereby helping to
provide additional performance improvements. Your z990 and z890 servers will require MCL updates.
Support is integrated in the z9-109 LIC. The performance assists are provided on the z9-109, z990,
and z890, as follows: HiperSockets (CHPID type IQD), all FICON features (CHPID type FCP), and all
OSA features (CHPID type OSD). Refer to the
Software requirements
section. Refer to Software Announcement
205-168
, dated July 27, 2005.

Enhanced application performance with FICON

Modified Indirect Data Address Word (MIDAW) facility:
The System z9 I/O architecture supports a new facility for indirect addressing, the MIDAW
facility, for both ESCON and FICON channels. The use of the MIDAW facility, by applications that
currently use data chaining, may result in improved FICON performance by reducing channel, director,
and control unit overhead.

Applications that use the following may benefit: DB2, VSAM, Partitioned Data Set Extended (PDSE),
Hierarchical File System (HFS), z/OS File System (zFS), and other data sets exploiting striping and
compression.

The MIDAW facility is exclusive to the z9-109, and is supported by ESCON (CHPID type CNC), and by
the FICON features (CHPID types FCV and FC). The MIDAW facility is exploited by z/OS. Refer to the
Software requirements
section.

Increased I/O addressing capability

Multiple Subchannel Sets (MSS):
MSS is designed to provide an increased number of subchannels. Two subchannel sets are now
available per LCSS and are designed to enable a total of 63.75K subchannels in set-0 and the
addition of 64K-1 subchannels in set-1.

With the Multiple Subchannel Set facility, one or two sets of subchannels may be configured to each
LCSS where subchannel set 0 (zero) may have from 1 to 63.75K subchannels defined, and subchannel set
1 (one) may have from 1 to (64K-1) subchannels defined. z/OS will allow Parallel Access Volume
Alias (PAV-alias) devices in the subchannel set 1 (one). MSS is designed to provide greater I/O
device configuration capabilities for large enterprises.

MSS is exclusive to the z9-109, and is supported by ESCON (CHPID type CNC), by all of the FICON
features supported on the z9-109 (CHPID type FC), and by z/OS and Linux on System z9. Refer to the
Software requirements
section.

63.75K subchannels:
The z9-109 addresses a maximum of 64K-1 subchannels in subchannel set 0 (zero) with 1024 (1K)
of these previously reserved for system use. IBM is making 768 of these 1K reserved subchannels
available for customer use. The increased addressable storage this represents may be significant.
For example, if you are using 3390 volume sizes and have 768 volumes of 54 GB/volume, this
represents 41 terabytes (TB) of increased storage addressability (54 GB/volume * 768 volumes = 41
TB). In addition, the IBM TotalStorage® DS8000 Series can be defined to attach 63.75K unit
addresses. Now with 63.75K in the host, there is symmetry between the server and storage subsystem.

63.75K subchannels is exclusive to the z9-109, and is supported by all channel types, and by z/OS,
z/VM, and Linux on System z9. Refer to the
Software requirements
section.

Increased number of FICON open exchanges:
The number of open exchanges is being increased from 32 to 64 on FICON Express2 channels on the
z9-109 to allow workloads with low to moderate control unit cache hit ratios to achieve higher
levels of activity rates per channel.

An updated FICON Express2 performance whitepaper is planned to be available in fourth quarter 2005.
Refer to the Web site

Increased connectivity in an I/O cage

Crypto, FICON, and OSA  A 40% increase in connectivity in one I/O cage:
You now have the capability to populate the 28 I/O slots in one I/O cage with any mix of the
following:

Up to 8 Crypto Express2

Up to 28 FICON Express2 or FICON Express

Up to 24 OSA-Express2 or OSA-Express

On z990 the maximum quantity of Crypto, FICON, and OSA features in combination in one I/O cage was
limited to 20 features.

This I/O connectivity enhancement is exclusive to the z9-109. There are no unique hardware or
software requirements.

FICON Express2

Up to 336 FICON Express2 channels supported on a z9-109:
The FICON Express2 features, with four channels per feature, support a link date rate of 1 or 2
Gbps autonegotiated and you can now install up to 336 channels (84 features) on the z9-109. Up to
240 FICON channels is supported on z990.

The FICON Express2 LX (#3319) and SX (#3320) features are offered in four channel increments, and
all channels on a single feature are of the same type, either LX or SX. You may also carry forward
to the z9-109 your current FICON Express2 features as well as your current FICON Express features
(#2319, #2320). Refer to the
Software requirements
section for operating system support for CHPID types FC and FCP. Refer also to the
Standards
section and to the
Sales Manual
on the Web.

FCP enhancement

N_Port ID Virtualization (NPIV):
N_Port Identifier Virtualization for Fibre Channel Protocol (FCP) channels (CHPID type FCP) is
designed to allow the sharing of a single physical FCP channel among operating system images,
whether in LPARs or as z/VM guests in virtual machines.

NPIV utilizes a recent extension to the InterNational Committee for Information Technology
Standardization (INCITS) Fibre Channel standard. This extension allows a Fibre Channel host bus
adapter (HBA) to perform multiple "logins" to a Fibre Channel fabric using a single physical port
(N_Port). The previous implementation of the standard required a single physical FCP channel for
each login. Each login uses a different unique port name, and the switch fabric assigns a unique
Fibre Channel N_Port identifier (FC N_Port ID) for each login. These virtualized FC N_Port IDs
allow a physical Fibre Channel port to appear as multiple, distinct ports, providing separate port
identification and security zoning within the fabric for each operating system image. The I/O
transactions of each operating system image are separately identified, managed, and transmitted, and
are processed the same as if each operating system image had its own unique physical N_Port.

NPIV exploits the capability to define multiple virtual FCP channels, each with its own unique Fibre
Channel port name and FC N_Port ID. By assigning different virtual port names to different
operating system images (running in LPARs or as z/VM guests in virtual machines), operating systems
can use the virtual FCP channels as if they were using dedicated physical FCP channels. In
particular, access controls based on the virtual port names may be applied in the Fibre Channel
fabric using standard mechanisms such as zoning in the switches and Logical Unit Number (LUN)
masking in the storage controllers.

NPIV offers improved FCP channel utilization and sharing among operating system images, joining
ESCON and native FICON in offering channel sharing through virtualization. This may help reduce
your hardware requirements and may help to facilitate infrastructure simplification.

NPIV allowing improved sharing and channel utilization of FCP channels among operating system images
in LPARs or virtual machines is exclusive to the z9-109, and is applicable to all of the FICON
features supported on the z9-109 (CHPID type FCP). Refer to the
Software requirements
section.

Note:
To utilize NPIV, the Fibre Channel switch to which the FCP channel directly attaches is required to
support NPIV. Support of NPIV is not required by cascaded switches (end nodes) or by the storage
controllers and devices accessed through the switch.

FCP point-to-point attachments:
When a FICON feature is configured as CHPID type FCP, IBM now supports the direct attachment of
devices (point-to-point connection), without the need for an intermediate Fibre Channel switch or
director. Point-to-point connections may be used to access data stored on these devices, and also
to IPL an operating system or other standalone program from such a device, using the SCSI IPL
feature. The no-charge SCSI IPL feature (#9904) is required to use the SCSI IPL function.

Note:
Point-to-point attachment of devices to an FCP channel, including the capability to IPL from such a
device, is also planned to be available for z990 and z890 (MCLs required). N_Port ID Virtualization
is not supported for point-to-point attachments.

FCP point-to-point attachments are supported on the z9-109, z990, and z890, by the FICON Express2
and FICON Express features (CHPID type FCP), and by z/VM for guest usage and Linux on System z9.
Refer to the
Software requirements
section.

FICON availability enhancements

Request Node Identification Data (RNID)  designed to assist with the isolation of FICON
cabling-detected errors:
In a fiber optic environment, with extended distances, resolution of fiber optic cabling
problems can be a challenge. To help facilitate resolution, the operating system can now request
the RNID data for each device or control unit attached to native FICON channels and display the RNID
data using an operator command.

RNID is exclusive to the z9-109, and is supported by the FICON Express2 and FICON Express features
(CHPID type FC), and by z/OS. Refer to the
Software requirements
section.

FICON link incident reporting
is designed to allow an operating system image (without operator intervention) to register for link
incident reports improving the ability to capture data for link error analysis. z/OS will display
this information on consoles and will also save it in the system log and in LOGREC.

FICON link incident reporting is exclusive to the z9-109, and is supported by the FICON Express2 and
FICON Express features (CHPID type FC), and by z/OS. Refer to the
Software requirements
section.

New for HiperSockets  Internet Protocol Version 6 (IPv6)

HiperSockets supports IPv6:
IPv6 support is now being offered for HiperSockets (CHPID type IQD). IPv6 is the protocol
designed by the Internet Engineering Task Force (IETF) to replace Internet Protocol Version 4
(IPv4) to help satisfy the demand for additional IP addresses.

IPv6 was introduced to expand the IP address space from 32 bits to 128 bits to enable a greater
number of unique IP addresses in support of the proliferation of devices now connecting to the
Internet, such as cell phones and PDAs.

The support of IPv6 on HiperSockets (CHPID type IQD) is exclusive to the z9-109, and is supported by
z/OS and z/VM. Refer to the
Software requirements
section. IPv6 support is currently available on the OSA-Express2 and OSA-Express features in the
z/OS, z/VM, and Linux on System z9 environments.

LAN connectivity  OSA enhancements

OSA-Express2 1000BASE-T Ethernet:
Today, IBM is expanding the family of OSA-Express2 features to include 1000BASE-T Ethernet,
supporting a link data rate of 10, 100, or 1000 Mbps over a copper infrastructure.

Concurrent LIC update capability  When properly configured, this capability is designed to avoid
a configuration off or on which can help to minimize the disruption of network traffic during an
update (applicable to CHPID types OSD and OSN).

The OSA-Express2 1000BASE-T Ethernet feature (#3366) is available on the z9-109. Refer to the
Software requirements
section for operating system support for CHPID types OSC, OSD, OSE, and OSN. Refer also to the
Standards
section and to the
Sales Manual
on the Web.

OSA-Express2 OSN  Open Systems Adapter for NCP:
The OSA-Express2 Gigabit Ethernet and 1000BASE-T Ethernet features
(#3364, #3365, #3366) now have the capability to provide channel
connectivity from System z9 operating systems to IBM Communication
Controller for Linux on zSeries (CCL) with the introduction of the Open
Systems Adapter for the Network Control Program (OSA for NCP) supporting
the Channel Data Link Control (CDLC) protocol.

OSA-Express2 OSN can help to eliminate the requirement to have any form
of external medium (and all related hardware) for communications between
the host operating system and the CCL image. Traffic between the two
images (operating system and CCL) is no longer required to flow on an
external LAN or ESCON channel; traffic can flow LPAR-to-LPAR.
OSA-Express2 OSN provides an efficient method of communication, and is
designed to create a secure and seamless integration of the host
operating system and CCL.

If you continue to require SNA solutions that require NCP functions, you
can now consider CCL as a migration strategy to replace your IBM
Communications Controllers (374x). The CDLC connectivity option enables
TPF environments to now exploit CCL.

The OSA-Express2 Gigabit Ethernet and 1000BASE-T Ethernet features
provide connectivity with a new CHPID type OSN (Open Systems Adapter for
NCP). Each host operating system that currently supports CDLC is
expected to be able to utilize CDLC to CCL without changes to the
operating system. OSA-Express2 OSN supports both SNA PU Type 5 and PU
Type 2.1 channel connectivity.

Utilizing existing SNA support (multiple transmission groups),
OSA-Express2 OSN support permits multiple connections between the same
CCL image and the same host operating system (such as z/OS or TPF) image.
The operating systems must reside within the same physical server (CPC)
as the CCL image.

OSA-Express2 OSN:

Is designed to appear to the operating systems as an ESCON channel
connected to a 374x device type which exploits existing CDLC protocols

Allows system administrators of the various operating systems to
configure, manage, and operate their CCL NCPs as if they were running in
an ESCON-attached 374x Communications Controller

Enables NCP channel-related functions such as loading and dumping of the
NCP

The CCL image connects to OSA-Express2 OSN using extensions to the QDIO
architecture. Linux support is in the QETH module.

OSA-Express2 OSN support is exclusive to the z9-109, to the OSA-Express2
Gigabit Ethernet SX, Gigabit Ethernet LX, and 1000BASE-T Ethernet
features (#3364, #3365, #3366), and requires the port to be configured as
CHPID type OSN, which can be configured on a port-by-port basis.
OSA-Express2 OSN is exclusively for internal communication, LPAR-to-LPAR.
Concurrent LIC update is supported. OSA-Express2 OSN is supported by
z/OS, z/VM, z/VSE, TPF, and Linux on System z9. Refer to the
Software requirements
section. Refer to the
Statement of General Direction
section for information on IBM Communication Controller for Linux on zSeries support of OSA-Express2
OSN.

VLAN management enhancement  Support of GVRP for ease of use and simplified management:
The OSA-Express2 features now support VLAN prioritization (a component of the IEEE 802.1
standard) to extend support of VLANs to help simplify networking administration and management of
VLANs. You may no longer be required to manually enter VLAN IDs at the switch.

Generic Attribute Registration Protocol (GARP) Virtual Local Area Network (VLAN) Registration
Protocol, also referred to as GARP VLAN Registration Protocol (GVRP), is an application defined in
the IEEE 802.1 standard that allows for the control of IEEE 802.1Q VLANs.

OSA communicates with GVRP-capable (IEEE 802.1Q) switches, registering its VLANs and dynamically
updating its table as the VLANs change. VLANs are designed to ease the administration of logical
groups of users  they can communicate as if they were on the same LAN. Traffic can be organized
by traffic patterns (such as TELNET, FTP, banking transactions) rather than by physical location.

Support of GVRP is exclusive to the z9-109, is applicable to all of the OSA-Express2 features when
in QDIO mode (CHPID type OSD), and is supported by z/OS and z/VM. Refer to
Software requirements
section.

OSA-Express2 Ethernet on the z9-109  Choose any combination:
The OSA-Express2 features provide you with functions and scalability to help satisfy the
demands of your global business. With data rates of 10 or 100 megabits per second (Mbps), 1 gigabit
per second (Gbps), and 10 Gbps, you can select the features that best suit your current and future
application requirements:

OSA-Express2 Gigabit Ethernet LX (long wavelength) (#3364)

OSA-Express2 Gigabit Ethernet SX (short wavelength) (#3365)

OSA-Express2 1000BASE-T Ethernet (#3366)

OSA-Express2 10 Gigabit Ethernet LR (long reach) (#3368)

You may also carry forward to the z9-109 your current OSA-Express2 features as well as your
OSA-Express features (#2364, #2365, #2366, #1364, #1365, #1366).

With multiple Ethernet options, you have the flexibility to deploy where applicable:

1000BASE-T Ethernet and a copper cabling infrastructure

Gigabit Ethernet and a multimode or single mode fiber optic cabling infrastructure

In addition to the above list of functions identified by CHPID type, over time the family of Open
Systems Adapters has added additional connectivity and functions. Here are some of the capabilities
and functions currently supported:

Layer 2 for protocol-independent packet forwarding

Spanned channels for sharing of OSA features among Logical Channel Subsystems (LCSSs)

Concurrent LIC update capability  When properly configured, this capability is designed to avoid
a configuration off/on, minimizing the disruption of network traffic during an update (applicable to
CHPID types OSD and OSN).

Extended Capacity Backup (CBU)

CBU is the temporary activation of CPs, IFLs, ICFs, and/or zAAPs for robust disaster recovery. The
CBU features provide the ability to concurrently increment the CP or specialty engine capacity of
your System z9 server, using Licensed Internal Code Configuration Control (LIC-CC), in the event of
an unforeseen loss of substantial System z9, zSeries, or S/390® computing capacity at one or more
of your eligible sites. The CBU features contain additional resources and alter related LICCC of
the target machine to an agreed upon configuration for up to a 90-day period of time. A single CBU
record containing a combination of CBU CP (#7820), CBU IFL (#7821), CBU ICF (#7822), and CBU zAAP
(#7824) can be added to the z9-109 models with no system power down and no associated re-IML or IPL.

CBU CP, IFL, ICF, and zAAP activations are mutually exclusive with On/Off CoD activation. Both CBU
(any type) and On/Off CoD can reside on the server, but only one can be activated at a time.

CBU test upgrades for the sole purpose of checking your ability in the event of an emergency are
provided. The CBU offering allows for up to five, 10-day tests over five years.

Contact your IBM representative for additional CBU information.

Customer Initiated Upgrade capacity  Technology on demand

Customer Initiated Upgrade (CIU) facility:
When your business needs additional capacity quickly, Customer Initiated Upgrade (CIU) is
designed to deliver it. CIU is designed to allow you to respond to sudden increased capacity
requirements by requesting a System z9 PU and/or memory upgrade via the Web, using IBM Resource
Link, and downloading and applying it to your System z9 server using your system's Remote Support
connection. Further, with the Express option on CIU, an upgrade may be made available for
installation as fast as within a few hours after order submission.

Permanent upgrades:
Orders (MESs) of all PU types and memory for System z9 servers that can be delivered by
Licensed Internal Code, Control Code (LIC CC) are eligible for CIU delivery. CIU upgrades may be
performed up to the maximum available processor and memory resources on the installed server, as
configured.

While capacity upgrades to the server itself are concurrent, your software may not be able to take
advantage of the increased capacity without performing an Initial Programming Load (IPL).

Temporary capacity

On/Off Capacity on Demand (On/Off CoD):
When your business needs short-term additional capacity, On/Off CoD is designed to deliver it.
On/Off CoD is designed to temporarily turn on CPs, ICFs, IFLs, and/or zAAPs. On/Off CoD utilizes
previously uncharacterized PUs (that is, those not purchased and assigned as a CP, ICF, IFL, or
zAAP), and purchased but unassigned CP capacity and/or purchased but unassigned IFLs that are
available within the server's current model configuration. On/Off CoD is delivered through the
function of CIU. To participate in this offering, you must have installed CIU Enablement (#9898)
and On/Off CoD Enablement (#9896). Activation of this capability is mutually exclusive with CBU
activation.

Both On/Off CoD and CBU can reside on the server, but only one can be activated at a time.

You may request and concurrently install temporary capacity through the CIU application on Resource
Link, and use that additional capacity for as long as needed.

Using this facility, you may add temporary capacity of the various PUs up to the maximum of
available PUs that are purchased but unassigned or unpurchased (uncharacterized). If unassigned or
uncharacterized PUs are available, you may:

Add a quantity of temporary CPs up to the quantity of permanently active CP plus unassigned CP
capacity

Add a quantity of temporary IFLs up to the quantity of permanently active IFL plus unassigned IFLs

Add a quantity of temporary ICFs up to the quantity of permanently active ICFs as long as the sum of
the temporary and permanent ICFs is less than or equal to 16, on the same server

You may similarly request and concurrently install a quantity of temporary zAAPs up to the quantity
of permanent zAAPs, with the limitation that the combined quantity of temporary zAAPs plus permanent
zAAPs may not exceed the combined quantity of temporarily active CPs plus permanently active CPs
plus unassigned CP capacity on the same server. You will be billed for associated usage through one
or more of the following features: On/Off CoD Active CP-Day (#9897), On/Off CoD Active IFL-Day
(#9888), On/Off CoD Active ICF-Day (#9889), or On/Off CoD Active zAAP-Day (#9893).

Pricing for unassigned CP capacity and unassigned IFLs

On/Off CoD pricing has been enhanced to provide reduced pricing when a temporary upgrade includes
activation of previously purchased but unassigned CP capacity and/or previously purchased but
unassigned IFLs. Now you may activate any amount of purchased but unassigned CP capacity or
purchased but unassigned IFLs on a temporary basis for a flat daily fee per engine type. There is
one flat daily fee for temporary usage of purchased but unassigned CP capacity and a second,
separate flat daily fee for temporary usage of purchased but unassigned IFLs. The offering is
designed such that when you activate purchased but unassigned capacity you'll be charged the lesser
of the flat daily fee or your standard On/Off CoD rate. Contact your IBM representative for
additional pricing information.

On/Off CoD test

On/Off CoD allows for a no-charge test. No IBM charges are assessed for the test, including IBM
charges associated with temporary hardware capacity, IBM software, or IBM maintenance. This test
can be used to validate the processes to download, activate, and deactivate On/Off CoD capacity
nondisruptively. Each On/Off CoD-enabled server is entitled to one no-charge test per contract.
This test may last up to a maximum duration of 24 hours commencing with the download and activation
of an On/Off CoD order. On/Off CoD tests which exceed 24 hours in duration will be treated in their
entirety as billable On/Off CoD upgrades. In addition to validating the On/Off CoD function within
your environment, you may choose to use this test as a training session for your personnel who are
authorized to activate On/Off CoD.

On/Off CoD no-charge test can be requested from the Web at Resource Link. Refer to

Extended staging of CIU-Express and On/Off CoD orders:
All CIU-Express and On/Off CoD orders may be staged for greater than
30 days. The orders may be staged for an extended period of time, unless
one of the following conditions occurs:

Order is canceled by customer

Server is no longer under warranty or IBM Maintenance Service Agreement

Preview  Server Time Protocol (STP)

IBM plans to make available a new time synchronization feature, STP, which is designed to provide
the capability for multiple System z9 and zSeries servers to maintain time synchronization with each
other. STP is planned to be the follow-on to the Sysplex Timer® (9037-002). The Sysplex Timer
and STP are designed to allow events occurring in different System z9, zSeries, and S/390 servers to
be properly sequenced in time.

STP is designed for servers that have been configured to be in a Parallel Sysplex® or a sysplex
(without a Coupling Facility) as well as servers that are not in a sysplex, but need to be time
synchronized. STP is designed to allow timing information to be sent between servers and CFs over
InterSystem Channel-3 (ISC-3) links configured in peer mode, Integrated Cluster Bus-3 (ICB-3) links,
or Integrated Cluster Bus-4 (ICB-4) links.

STP is designed to:

Allow clock synchronization for the z9-109, z990, and z890 servers and CFs without requiring the
Sysplex Timer

Support a multisite timing network of up to 100 km (62 miles) over fiber optic cabling,
allowing a Parallel Sysplex to span these distances

Allow use of dial-out time services to set the time to an international time standard (such as
Coordinated Universal Time [UTC]) as well as adjust to UTC on a periodic basis

Allow setting of local time parameters, such as time zone and Daylight Savings Time

Allow automatic updates of Daylight Savings Time

STP is planned to be available as a feature on the z9-109, z990, and z890, and to be supported by
z/OS V1.7 (PTFs will be required to enable STP support).

Implementation Assistance Program (IAP):
IBM plans to make available an IAP to allow you to accelerate the adoption of STP with IBM's
assistance. The assistance being planned for this program includes consultation, the review of your
migration plans, and technical support. The IAP is planned to begin in October 2005 and be
made available through 2006.

Coupling connectivity for Parallel Sysplex

IC, ICB, and ISC-3 on the z9-109:
The z9-109 supports Internal Coupling channels (ICs), ICB-3, ICB-4, and ISC-3 (peer mode) links
for passing information back and forth in a Parallel Sysplex environment.

ICs are used for internal communication between CFs defined in LPARs and z/OS images on the same
server. Up to a maximum of 32 can be defined per server.

ICBs are used for server-to-server communication over short distances, using 10 meter (33 feet)
copper cables, of which 3 meters (10 feet) is used for internal routing and strain relief.

ICB-3 (#0993) supports a link data rate of 1 gigabyte per second and is used to connect z9-109s to
z900s and z800s up to a maximum of 16 links.

ICB-4 (#3993) supports a link data rate of 2 gigabytes per second and is used to connect
z9-109s to z9-109s, z990s, and z890s up to a maximum of 16 links.

ISC-3s (#0217, #0218, #0219) support a link data rate of 2 gigabits per second and are used for
server-to-server communication at distances up to 10 km (6.2 miles) using 9 micron single mode fiber
optic cables. ISC-3s are supported exclusively in peer mode (CHPID type CFP).

The maximum number of external Coupling links combined (ICs, ICB-3s, ICB-4s, and active ISC-3 links)
cannot exceed 64 per server. Refer to the
Sales Manual
on the Web for more information on ICs, ICBs, and ISC-3.

ICB-2 links no longer supported:
ICB-2 links were used to support Parallel Sysplex connectivity
between 9672 G5 and G6 servers and z990, z900, and z800 servers. ICB-2
links are no longer supported. Withdrawal of support of ICB-2 links on
the z9-109 satisfies the Statement of General Direction in Hardware
Announcement
103-142
, dated May 13, 2003.

ISC-3 links in compatibility mode no longer supported:
Attachment of ISC-3 links on the z9-109 to HiPerLinks (ISC-2) on G5
and G6 servers is not supported. ISC-3 compatibility mode is not
supported on the z9-109 (CHPID types CFS and CFR).

Withdrawal of support of ISC-3 links in compatibility mode on the z9-109
satisfies the Statement of General Direction in Hardware Announcement
104-118
, dated April 7, 2004.

GDPS enhancements

Improved availability with enhanced recovery support for a CF structure duplexing environment

Performance improvements for System Logger in a z/OS Global Mirror (previously known as XRC)
environment

Unplanned HyperSwap IOS Timing trigger:
If a disk subsystem experiences a "hard failure" such as a boxed device, rank array failure, or
disk subsystem failure, current versions of GDPS/PPRC and GDPS/PPRC HyperSwap Manager (GDPS/PPRC HM)
are designed to detect this and automatically invoke HyperSwap to transparently switch all primary
PPRC disks with the secondary disks without requiring z/OS and z/VM applications to be quiesced.

With this enhancement, planned to be available third quarter 2005, GDPS/PPRC and GDPS/PPRC HM will
provide new function designed to autonomically invoke HyperSwap when customer-defined I/O timing
thresholds are exceeded. This may allow you to tailor unplanned HyperSwap for conditions when a
disk subsystem is experiencing soft failures such as a nonresponsive disk subsystem. This function
is designed to be applicable to all vendor disk subsystems as long as the vendor meets the specific
functions of the Metro Mirror architecture.

Preview  GDPS V3.3 functions

HyperSwap at disk subsystem level within a data center:
GDPS/PPRC HyperSwap Manager is designed to add the capability to provide continuous
availability of data within a single data center. Previously, a planned outage of a single disk
subsystem or an unplanned failure of a single disk subsystem invoked a HyperSwap of all the remote
copy pairs defined to GDPS. The remote copy pairs could potentially span multiple disk subsystems.

With this enhancement, GDPS/PPRC HyperSwap Manager is designed to optionally only invoke a HyperSwap
for individual disk subsystems, as long as both the primary and secondary disk subsystems are
located in the same data center. This allows you to maintain backup capability for the remaining
disk subsystems during the window of a planned or unplanned outage. In addition, system management
is simplified since only a single subsystem will need to be resynchronized to return to the original
configuration.

GDPS enhanced recovery support:
The current GDPS/PPRC failover has potentially long, variable recovery application restart
times. The CF structure data may not be time-consistent with a "frozen" copy of data on disk, so
GDPS must discard all CF structures at the secondary site when restarting workloads. This results
in loss of "changed" data in CF structures. The customer must execute potentially long-running and
highly variable data recovery procedures to restore the lost data.

With GDPS enhanced recovery, if you specify the FREEZE=STOP policy and duplex the appropriate CF
structures, when CF structure duplexing drops into simplex, GDPS is designed to direct z/OS to
always keep the CF structures in the site where the secondary disks reside. This is designed to
ensure that the secondary PPRC volumes and the CF structures are time consistent, thereby helping to
provide consistent application restart times without any special recovery procedures.

System logger
is planned to provide new support for XRC+ by allowing you to choose asynchronous writes to staging
data sets for logstreams. Previously, all writes had to be synchronous. This limited the
throughput for high-volume logging applications such as WebSphere®, CICS®, and IMS. The
ability to do asynchronous writes can allow the use of z/OS Global Mirror (previously known as XRC)
for some applications for which it was not previously practical.

GDPS/XRC is planning to extend its automation to support XRC+. Planned to be available fourth
quarter 2005, it is expected to provide the ability to configure and manage the staging data set
remote copy pairs.

GDPS V3.3 is planned to be available fourth quarter 2005. GDPS is designed to work in conjunction
with the z9-109, z990, z890, z900, and z800 servers. For a complete list of other supported
hardware platforms and software prerequisites, refer to the GDPS Web site

GDPS/Global Mirror
is planned to be available in October 2005. GDPS/Global Mirror
Services, including the licensed GDPS Automation Code, may be delivered
to customers prior to October 2005. Contact your IBM representative
or send an e-mail to gdps@us.ibm.com for information regarding
participation in an early implementation.

Section 508 of the U.S. Rehabilitation Act

System z9 109s are capable on delivery, when used in accordance with IBM's associated documentation,
of satisfying the applicable requirements of Section 508 of the Rehabilitation Act of 1973, 29
U.S.C. Section 794d, as implemented by 36 C.F.R. Part 1194, provided that any Assistive Technology
used with the product properly interoperates with it.

The System z9 109 represents a continuing evolution of the mainframe. With a modular design for
affordable scalability, the z9-109 Model S54 is designed to provide up to a 95% improvement in
total system capacity compared to the z990 Model D32, a 40% increase in the number of FICON
channels, double the amount of available memory, double the number of supported LPARs (up to 60),
one third more internal I/O paths, and an increased number of open exchanges (concurrent I/O
operations) that may be active simultaneously from 32 to 64 per FICON Express2 channel.

With a design for affordable scalability, the z9-109 is positioned to continue to enable investment
protection as well as improved price and performance with upgrades. Built on a foundation that is
designed to improve recovery for unplanned outages, the z9-109s innovative technologies are intended
to help reduce planned outages by offering improved capabilities in the areas of downloading new
function updates as well as upgrading and repairing memory, books, and I/O.

The balancing of hardware and operating system interoperability continues with Multiple Subchannel
Sets (MSS) and the Modified Indirect Data Address Word (MIDAW) facility. The MIDAW facility may
benefit applications that use the following: DB2, VSAM, PDSE, HFS, zFS, and other data sets
exploiting striping and compression.

The z9-109 is intended to provide the ability to improve application performance, increase the
number of users and supported transactions, increase scalability, and consolidate workloads beyond
what is available on a z990.

Note:
The comparison of the z9-109 Model S54 and the z990 Model D32 is based on the LSPR mixed
workload average.

Sysplex Timer  Plans to withdraw from marketing

IBM intends to withdraw the Sysplex Timer Model 2 (9037-002) from marketing in 2006. When the
withdrawal from marketing is announced, no orders for Sysplex Timer Model 2s or its features
will be accepted after the effective date.

A Sysplex Timer or equivalent (refer to Server Time Protocol [STP] preview in the
Description
section) is a mandatory hardware requirement for a sysplex consisting of more than one server.
Currently, the Sysplex Timer provides the synchronization for the Time-of-Day (TOD) clocks of System
z9, zSeries, and S/390 servers, so that events occurring in different servers are properly sequenced
in time.

All strategic planning should include a plan to migrate from a Sysplex Timer Model 2 network
(also referred to as an External Time Reference [ETR] network) to an STP network, when STP
becomes available. Evaluate your current and future requirements for Sysplex Timers.

Future z/VM support on the z9-109

IBM intends to provide future enhancements to z/VM supporting the following z9-109 functions:

System and guest exploitation of HiperSockets supporting IPv6

Improved memory management between z/VM and Linux on System z9

Simplified networking administration and management of VLANs with support for GARP VLAN Registration
Protocol (GVRP) using OSA-Express2

Connectivity using ICB-3 links to be phased out

IBM intends to phase out Integrated Cluster Bus-3 links (ICB-3 links) over time. IBM plans to
support ICB-3 links on z9-109 through the lifecycle of z9-109.

Enhancements to network connectivity

On February 15, 2005, IBM announced the IBM Communication Controller for Linux on zSeries
(CCL) V1.1. This product is intended to provide a migration path for customers using SNA
applications to communicate with Business Partners. In the next release of CCL IBM intends to
provide enhancements in network connectivity such as the Channel Data Link Control (CDLC) protocol
using OSA-Express2 OSN (OSA for NCP), DLSw, and an open interface for X.25 (NPSI). For more
information on this product refer to

Future z/VSE offering

IBM TotalStorage directions

IBM TotalStorage DS8000 Series enhancements

IBM TotalStorage z/OS Global Mirror (XRC) and IBM TotalStorage Global Mirror (asynchronous PPRC)
capability on the IBM TotalStorage DS8000 Series to enable the use of consistency groups that can
span both remote mirroring products for enhanced business continuity. This capability is intended
to help customers maintain and leverage their investment in z/OS Global Mirror (XRC) while
implementing Global Mirror (asynchronous PPRC) for heterogeneous server environments.

A continuous data protection function on the IBM TotalStorage DS8000 Series for System z9
environments. This capability is intended to provide support for enhanced data resiliency and
business continuity.

IBM TotalStorage SAN Volume Controller (SVC):
To enhance the interoperability of the IBM TotalStorage SAN Volume Controller, IBM is planning
to provide SVC support for Linux on System z9 environments. This is designed to allow System z9
hosts and supported open system hosts to share storage pools created by the SAN Volume Controller.

Provision of an enhanced Import/Export function designed to allow sets of cartridges to be
interchanged between VTSs and/or Peer-to-Peer (PtP) VTSs or exported for storage in a remote vault.
This enhancement is designed to allow virtual volumes to be directed to a VTS volume pool,
subsequently exported on physical cartridges under host control, and imported into another VTS under
host control.

Extension of the PtP VTS  support for full-duplex virtual volume replication between three sites.
DFSMS parameters are designed to provide policy-based copy management to control the source and
target VTSs, the preferred routing, and the mode of operation.

IBM TotalStorage SAN File System (SFS):
SFS was designed to help you manage the growing complexities and rising costs associated with
dramatic growth in disk storage requirements. IBM continues to expand on the concept of
system-managed storage by working to extend some of the storage management capabilities of DFSMS to
open system environments to support improvements in storage asset utilization and administrator
productivity.

IBM plans to increase the range of IBM TotalStorage SAN File System supported hosts to include the
31-bit SUSE LINUX Enterprise Server 8 (SLES 8) client distribution running under z/VM on System z9
and zSeries. This support is designed to apply exclusively to hosts acting as the SFS client in a
System z9 or zSeries server running SUSE SLES 8. This extension of host support for SFS is intended
to support increased data sharing between UNIX, Linux, Windows, and mainframe platforms.

IBM TotalStorage encryption:
To address customers' growing concern with data security, IBM is planning for the development,
enhancement, and support of encryption capabilities within storage environments such that the
capability does not require the use of host server resources (so called "outboard" encryption
capabilities). This includes the intent to offer, among other things, capabilities for products
within the IBM TotalStorage portfolio to support outboard encryption and to leverage the key
management functions provided by the Integrated Cryptographic Service Facility (ICSF).

All statements regarding IBM's plans, directions, and intent are subject to change or withdrawal

Specified operating environment

Physical specifications

2094 servers:
The mechanical package for the z9-109 is designed to conform to EIA guidelines for frames.
Packaging for new build z9-109s is two frames. Upgrades will be contained within the two frames
initially shipped. Note that height reduction for transport is available. Keep in mind that the
height of the z9-109 is equal to the height of a z990 or z900 that has been reduced in height. When
considering placement of a z9-109, review clearances for doors to be opened. A new build z9-109 at
the minimum level will consist of two frames with one I/O cage. A new build z9-109 at the maximum
level will consist of two frames with three I/O cages. A 60 amp service is required.

Contact your IBM representative for the available width and height reduction transport options for
return of z900 and z990 servers. There is no width reduction feature for z990. There is a height
reduction for shipping feature available for z9-109 (#9975). Keep in mind that the z9-109 is equal
in height to a z990 or height-reduced z900. Therefore, one may not automatically assume that a
z9-109 reduction is necessary due to their experience with z900. Determine the height and only
order as necessary.

Standards:
The FICON Express2 features are designed to conform to the following standards:

This standard was developed by Task Group T11 of Accredited Standards Committee INCITS during
2002-2003. The standards approval process started in 2002.

SB-3 is a mapping protocol, referred to as an FC-4. An FC-4 is a mapping protocol that maps a
particular Upper Level Protocol (ULP) instance to Fibre Channel. The SB-3 ULP is based on the
SB-2 ULP, which is based on the Single-Byte Command Code Set.

IBM devices previously attached to IBM S/390® and zSeries servers are
supported for attachment to System z9 channels, unless otherwise noted.
The subject I/O devices must meet ESCON or FICON architecture
requirements to be supported. I/O devices that meet OEMI architecture
requirements are supported only using an external converter.
Prerequisite Engineering Change Levels may be required. For further
details, contact IBM service personnel.

While the z9-109 supports devices as described above, IBM does not commit
to provide support or service for an IBM device that has reached its End
of Service effective date as announced by IBM.

Note:
IBM cannot confirm the accuracy of performance, compatibility, or any
other claims related to non-IBM products. Questions regarding the
capabilities of non-IBM products should be addressed to the suppliers of
those products.

Planning information

Customer responsibilities

Customer responsibilities for site preparation:
Information on customer responsibilities for site preparation can be found in publications
available in the Library section of Resource Link at

IGS has the expertise and personnel available to effectively plan and
deploy the appropriate cabling with the future in mind. These services
may include planning, consultation, cable selection, installation, and
documentation, depending upon the services selected.

These services are designed to be right-sized for your products or the
end-to-end enterprise, and to take into consideration the requirements
for all of the protocols and media types supported on the System z9 and
zSeries (for example, ESCON, FICON, Coupling Links, OSA) whether the
focus is the data center, the Storage Area Network (SAN), the Local Area
Network (LAN), or the end-to-end enterprise.

IBM Networking Services
are designed to deliver convenient, packaged services to help reduce the
complexity of planning, ordering, and installing fiber optic cables. The
appropriate fiber cabling is selected based upon the product requirements
and the installed fiber plant.

The services are packaged as follows:

Under the
zSeries fiber cabling services
umbrella there are
three
options to provide individual fiber optic cables (jumper cables,
conversion kits, and MCP cables) for connecting to the z9-109, z990,
z890, z900, and z800, each option incorporating a specific set of
services.

Option 1  Fiber optic jumper cabling package. IBM does the detailed
planning. This option includes planning, new cables, installation, and
documentation. An analysis of the System z9 and zSeries channel
configuration, I/O devices, and any existing fiber optic cabling is
required to determine the appropriate fiber optic cables.

Option 2  Fiber optic jumper cable migration and reuse for a zSeries
to zSeries or zSeries to System z9 upgrade. IBM organizes the existing
fiber optic cables based upon the System z9 and zSeries connection
details. Relabeling, rerouting, and reconnection to the appropriate
channels is performed. New cables are not offered as a part of this
option.

Option 3  Fiber optic jumper cables and installation. The customer
tells us what they need. They do the detailed planning. The service
includes new cables, installation, and documentation. Planning and
providing the list of required cables are customer responsibilities.

Options 1 and 2 can be combined within one statement of work to provide
comprehensive upgrade coverage.

Under the
enterprise fiber cabling services
umbrella there are
two
options to provide IBM Fiber Transport System (FTS) trunking commodities
(fiber optic trunk cables, fiber harnesses, and panel-mount boxes) for
connecting to the z9-109, z990, z890, z900, and z800.

Option 1  zSeries fiber optic trunk cabling package. IBM reduces the
cable clutter under the floor. An analysis of the z9-109, z990, z890,
z900, and z800 channel configuration and any existing fiber optic cabling
is performed to determine the required FTS fiber optic trunking
commodities (trunk cables, harnesses, and panel-mount boxes). This
option includes System z9 and zSeries planning, FTS fiber optic trunking
commodities, installation, and documentation. This option does not
include enterprise-level planning.

Cabling responsibilities:
Fiber optic cables, cable planning, labeling, and placement are all
customer responsibilities for new installations and upgrades. Fiber
optic conversion kits and MCP cables are not orderable as features on a
z9-109. Installation Planning Representatives (IPRs) and System Service
Representatives (SSRs) will not perform the fiber optic cabling tasks
without a services contract.

The following tasks are required to be performed by the customer prior to
machine installation:

All fiber optic cable planning.

All purchasing of correct fiber optic cables.

All installation of any required MCP cables.

All installation of any required Conversion Kits.

All routing of fiber optic cables to correct floor cutouts for proper
installation to server.

Use the Physical Channel Identifier (PCHID) report or the report from the
Channel Path Identifier (CHPID) Mapping Tool to accurately route all
cables.

All labeling of fiber optic cables with PCHID numbers for proper
installation to server.

Use the PCHID report or the report from the CHPID Mapping Tool to
accurately label all cables.

Additional service charges may be incurred during the server installation
if the above cabling tasks are not accomplished as required.

The table lists the connectors and cabling supported for each of the
features available for ordering on a z9-109 (identified with an "*" next
to the feature number). For convenience, those features carried forward
on an upgrade from the z900 or z990 are also listed.

Installability:
The average installation time for a z9-109 is approximately 16 man
hours. This does not include planning hours. This assumes the
Pre-Installation Configuration Service, a full System Assurance Product
Review, and implementation of the cable services have been performed.
See your IBM representative for details on these services.

Security, auditability, and control

The z9-109 uses the security and auditability features and functions of host hardware, host
software, and application software.

The customer is responsible for evaluation, selection, and implementation of security features,
administrative procedures, and appropriate controls in application systems and communications
facilities.

IBM Global Services has transformed its delivery of hardware and software support services to put
you on the road to higher systems availability. IBM Electronic Services is a Web-enabled solution
that provides you with an exclusive, no-additional-charge enhancement to the service and support on
the IBM System z9 109. You should benefit from greater system availability due to faster problem
resolution and preemptive monitoring. IBM Electronic Services is comprised of two separate, but
complementary, elements: IBM Electronic Services news page and IBM Electronic Service Agent.

IBM Electronic Services news page provides you with a single Internet entry point that replaces the
multiple entry points traditionally used by customers to access IBM Internet services and support.
The news page enables you to gain easier access to IBM resources for assistance in resolving
technical problems.

The IBM Electronic Service Agent is no-additional-charge software that resides on your IBM System z9
109. It is designed to proactively monitor events and transmit system inventory information to IBM
on a periodic, customer-defined timetable. The IBM Electronic Service Agent tracks system
inventory, hardware error logs, and performance information. If the server is under a current IBM
maintenance service agreement or within the IBM warranty period, the Service Agent automatically
reports hardware problems to IBM. Early knowledge about potential problems enables IBM to provide
proactive service that maintains higher system availability and performance. In addition,
information collected through the Service Agent will be made available to IBM service support
representatives when they are helping answer your questions or diagnosing problems.
